Zoospore
Zoospore
Zoospore (/ˈzoʊəˌspɔːr/; from the Greek ζῷον (zōion), meaning "animal", and σπορά (sporá), meaning "seed") is a motile asexual spore that uses a flagellum for locomotion. Also called a swarm spore, these are created by some algae, fungi, and protozoa to propagate themselves.
Etymology
The term "zoospore" is derived from the Greek words ζῷον (zōion), meaning "animal", and σπορά (sporá), meaning "seed". This reflects the spore's ability to move independently, much like an animal, and its role in reproduction and propagation, similar to a seed.
Function
Zoospores are produced in a sporangium, from which they are released for dispersal. They move using a whip-like tail, or flagellum, and once they reach a suitable environment, they lose their flagellum and grow into a new organism.
Types
There are two types of zoospores: flagellated spores, which have one or two flagella at the front end, and amoeboid spores, which move without flagella.
